4 Claims.

` and convenient, thoroughly eilicient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above objects in View as will appear as the description proceeds, the invention consists in certain novel features of construction,

and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a fragmentary inside elevation of a pair of window sashes showing my attachment mounted in place,

Figure 2 is a sectional view taken substantially on the line 2--2 of Figure 1.

Figure 3 is a top plan view of the attachment.

Figure e is a fragmentary elevation showing the cartridge carrier plate in raised position,

Figure 5 is a fragmentary perspective view of an intermediate portion of the back or bracket plate, and

Figure 6 is a detail sectional view through the attachment clip and adjacent portions of the back or bracket plate.

Referring to the drawings in detail it will be seen that numeral 5 denotes a back or bracket plate provided intermediate its ends with a square opening 6 and crimped a slight distance below the opening as at 7 and a slight distance below the crimp '7 being offset as at 8. Numeral 9 denotes a spring clip having a crimp portion 10 to iit over the crimp portion 7. This clip is fixed to a square plate 12 of less area than the opening 6. A screw le fastens the plate and clip to a side rail 15 of an upper sash U. The bracket plate is held in place by this clip 9 as is best shown in Figure 6 and may be easily and quickly mounted in place on the rail 15 or detached therefrom. The upper end of the plate 5 merges into a narrowed portion 17 which is bent or extended so as to provide a downwardly and inwardly inclined extension 18 terminating in a reduced hammer head 19. A cartridge carrying plate 20 is hingedly mounted as at 2l on the bracket plate and carries a spring clip 22 formed with an eye 23 under which a paper cartridge or the like may be mounted and brought into engagement with the hammer headvwhen the plate 20 is swung upwardly bythe action of a coil spring 24 one end of which is fixed to the plate 2O and the other end fixed to the plate 5. A hook 25 is mounted on the free end of the plate 20. C

A V-shaped spring element S comprises a relatively short arm 26 secured under the offset portion 8 of the plate 5 and a relatively long arm 27 terminating in an eye 28 to engage with the hook 25.

With the device in set position as shown in Figure 2 it will be seenthat when the lower sash L is raised the upper rail 30 thereof will engage the arm 27 and move it toward the upper sash L,

U until the eye 28 is disengaged from the hook 25.

Then the spring 24 is free to swing the plate 20 up so that the cap held by the eye 23 of the spring clip 22 `will strike the hammer head and explode thereby giving an audible signal. As the sash is moved still further up the spring S will function as a wedge stop since the eye 28 will engage the coil spring 24 thereby preventing the lower sash or the upper sash from being completely opened to permit the access of an unauthorized person .g

into the building or the like.

It is thought that the construction, operation, utility and advantagesI of this invention will now be clearly understood without a more detailed description thereof.

The present embodiment of the invention has i been described in considerable detail merely for the purposes of exempliiication since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to Without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. A safety window device of the class described comprising a bracket plate, a cartridge carrier plate hingedly mounted on the bracket plate, a hammer head mounted at one end of the bracket plate, a spring element mounted at the other end of the bracket plate and having means detachably engaged with the cartridge carrier plate, and spring means associated with the cartridge carrier plate to normally swing it in a position to abut the hammer head.

2. A safety window device of the class described comprising a bracket plate, a cartridge carrier plate hingedly mounted on the bracket plate, a hammer head mounted at one end of the bracket plate, a spring element mounted at the other end of the bracket plate and having means detachably engaged with the cartridge carrier plate, and spring means associated with the cartridge carrier plate to normally swing it in a position to abut the hammer head said bracket plate being provided with an opening, a spring clip adapted to be secured to a sash and extended through said opening to hold said bracket plates secured in place.

3. A safety Window device of the class described comprising a bracket plate, a cartridge carrier plate hingedly mounted on the bracket plate, a hammer head mounted at one end of the bracket plate, a spring element mounted at the other end of the bracket plate and having means detachably engaged with the cartridge carrier plate, and spring means associated with the cartridge carrier plate to normally swing it in a position to abut the hammer head, said bracket plate being provided with a square opening, a spring clip and a square plate on the clip to t into said opening and adapted to be secured to a sash.

4. A device of the class described comprising a bracket plate having one end extended over upon itself at an acute angle and terminating in a hammer head, the other end of the plate being offset, a V-shaped spring having a relatively short arm xed under the offset portion of the bracket plate and the other arm being relatively long and terminating in an eye, a plate hinged on the bracket plate, means for mounting a cartridge on the second mentioned plate, said second mentioned plate having a hook with which said eye is engageable, and spring means associated with said second mentioned plate to normally swing it up into engagement with the hammer head When the long arm of the spring is actuated to free the eye from said hook.
